Turf algae are becoming more abundant on coral reefs worldwide, but their effects on other benthic organisms remain poorly described. To describe the general characteristics of competitive interactions between corals and turf algae, we determined the occurrence and outcomes of coral-turf algal interactions among different coral growth forms (branching, upright, massive, encrusting, plating, and...

Background An economical strategy for producing microalgae as biofuel feedstock is driven by the freshwater and nutrients input. In this study, seawater was applied to limnetic algal cultivation and the behavior of algae in seawater media was observed including growth, lipid synthesis, and ultrastructure. To make seawater cater algae, a kind of wastewater, anaerobically digested effluent from k...

Algae-based fuel are considered a promising sources of clean energy, and because it has many advantages over traditional biofuel, research and business ventures have driven into developing and producing Algal-biofuel. But its production stages create a cost structure that it is not competitive with traditional fuels. Therefore, cost becomes the main obstacle in commercial production purpose. Ho...

Algal bioproducts are of growing interest to agriculture because their biodegradable nature, ability restore soil fertility, and capacity for plant growth regulation, nitrogen fixation, carbon sequestration. Plants respond a suite hormones; auxins present in algal extracts or secreted exogenously by living algae may be partially responsible the stimulation growth. Auxins major class phytohormon...

Enclosure experiments with all combinations of NH4 and PO4 treatments were carried out in the northern Baltic coastal zone during the post–spring bloom growth season. Empirical models were used to identify the important 3d treatment effects on the state and process variables governing the main plankton compartments. Moreover, dilution experiments revealed the main nutrient sources for algal gro...

Woloszynskia species are dinoflagellates in the order Suessiales inhabiting marine or freshwater environments; their ecophysiology has not been well investigated, in particular, their trophic modes have yet to be elucidated. Previous studies have reported that all Woloszynskia species are photosynthetic, although their mixotrophic abilities have not been explored. We isolated a dinoflagellate f...

One of the questions associated with the development of a cost-effective phosphorus management strategy for a waterbody concerns whether the control program should be based on total phosphorus or on algal available phosphorus entering the waterbody. Until now, eutrophication control programs have been based largely on the control of any form of phosphorus that was amenable to control, irrespect...
